'ject to provide a means whereby a flat sea-m.

may be used in connectionwith a lock stitch uponthe ordinary spindle type glove sew ing machine.

Heretofore in the manufacture of that type of gloves commonly known as" pique gloves, wherein a fiat seam exists throughout the construction thereof, it has been the custom to fit up or partially sew the same upon a flat bed machine in orderthat a lock stitch may beproduced, and to complete or close the glove on the standard glove sewing machine, producing-a chain stitch.- -.This

' naturally produces a clumsy and 'unpreposthereof;

sessing appearanceon the part of the glove andincreases the cost of labor, the amount of thread, and, in fact, increases the expense. in all branches of .the manufacture The present produce flat seamed gloves, and at the same time sew,'fit and close the same with a lock stitch throughout.

The present invention does not embodyall of the features as completed, but covers the thread hook'attachment, a coiiperating shuttle mechanism forming the subject matter of the co-pending application filed September 8, 1911, Serial No. 648,879,

- *With the above and other objects in View, this invention consists '-in the combination, construction and arrangement of part-mall as hereinafter more fully described-,claimed and illustrated in the accompanying drawings, whereini Figure 1 is chine, illustrating the cooperating needle and needle rod, and the thread book form-.

ing the subject matter of the present invention, and also the operating mechanism thereof; 2 is a vert cal sectionftaken invention contemplates the provision of a means whereby the spindle. type glove sewing machineimay be used-to the bed of the machine and-has mounted for reclprocation therein, a slide on which is a front elevation of'a'msh' along-line 22 of 1'; Fig. 3 is a, transverse section taken along line 3-3 of Fig.'

2; Fig. 4 is a diagrammatical view of the path of the upper terminal of the thread. hook.

The thread hook attachment for glove sewin machines, formingthe subject mattero the present invention, is provided in order that the thread carried by the needle may be engaged after the same has pierced the leather, drawing said thread through the work supporting spindle and placing the same .in such a position that it will-be engaged by the shuttle or looper (illustrated in the present invention, but ''forming the subject matterv of the. co-pending application filed herewith), said shuttle or looper then engaging the thread to form a ortionof the lock stitch,-as will hereina ter be more fully described. The work support-.

;ing spindle used in;the present invention is necessarily hollow, having a flared enlarge-' ment at its lower terminal, in order that the same may readily coiiperate with the shuttle or looper for the return of the thread,

through the work supporting spindle after the same-has cooperated with the thread carried by the bobbin.

A standard needle rod carrying any suitable needle, reciprocatesabove the work 1 supporting spindle, said needle being adaptedto enter said spindle at ire-determined intervals, after the same has pierced the leather or goods. p

A guide is mounted on the under face of,

vertically mounted for oscillation a bearing,

through which the thread hook, forming Lt-ical rod extends below the bed of the ma chlne and is adapted to remain stationary,

having mounted thereon a suitable slide, to

which the lower terminal of the thread hook is pivotally secured.

The operationandfunction of the various elements of the machine will hereinafter be more full described, setting forth fully the timing 0 the thread engaging and disengaging intervals. v Referring more particularly'to the draw ings 10 indicates a-fragmentary section of a,

bed of a glove sewing machine, havin a opening 11 therein, adjacent to whic' -i's no I mounted v a bearing 12, which cooperates with an auxiliary bearing 13 for the sup ort ofthe spindle base 14. The spindle ase 14 is apertured for the passage of the strumentality of the clamping plate 29. The opening of the "bearing 23 is of suflicient size to permitthe reciprocation of the shank, 32 therethrough. The upper or smaller terminal of the shank 32 is bent to- 79 ward the bearing 12, as at- 33, .forming a vertical oflset portion-34, which is bent toward the front'of the machine to form a hook, 35. .This thread hook operates in close proximity with the shuttleor l'ooper indicated generally as A, in order that the a'nd-operably' mounted within the bearing A standard needle rod 17, carrying any suitable needle 18 is'mounted for recipro- M ation above the spindle in such a manner -that upon-the movement of the needle rod,

said needle will enter'the spindle, at the same time piercing .the leather or goods 10- thread engaged by "theh'ook 35*may be readily transferred to said shuttle or looper.

. Any suit-able means36 is providedwhereby the slide 21' maybe reciprocated in the guide 19, saidmeans and the tim'ingmecha nlsm therefor not forming a part of the present application, and consequently not illuslocated substantially'-. directly below the theloweriterminal or base of the thread hated thereon, at pre-determined intervals. 80." A guide'19 is mounted transversely on the ide of the machine bed 10, adjacent to the openin '11, and carries at each terminal thereo vertical bearings 20, in which re ci'procates the slide 21, said slide being op- 25 erated by any shit-able mechanism for the- ,son of the fact that the same does not form purpose of timin the operation thereof, as a partof the present application; will hereinafter e more fully described. v In'operation, the needle'18 carryingthe An Ofl-Set bracket 1 centranySecuI-ed t thread 38 pierces the goods located upon the the'slide21 and has a circular vertical bear- Spindle-15 and enters said spindle carrying no in 23 mounted. therein throughihe inst-rm the thread 38 therewith, the free terminal of. 'tmentality of the trunnions 24, formed or said th'read being retained within the goods, v4 the wi' 'u d to r ide ofth b i g and consequently above the upper end'ofthe v '23 and operating between the offset bracket spindle, thereby'forrning a loop adjacent to 22 andthe slide 21. This,cona'truction z. e. the lower terminal of the needle. As the 35 the elimination of .theepassage of a pin needle 1 8 enters the spindle, the'slide 21 t rough the bearing23 is suchlthat the same moves to .the left (referring to Fig. 2) will notin any way-interfere with the verticarrying the thread hook 35 referred to call opening'25 formed Withinth'ebeariug generally as B in a similar direction, in 23, for the reciprocation of-thg thread hook; order that the same will not interferew'ith 40" A'dep'endent rod 26 iscarriedby'the uideoperation of the bobbin hook, after which iaand-is, in t-heconstruction of the mac ine, the slide 21 moves to the right, causingv the thread hook B to assume a substantially I vertical position. The" slide 27 then moves upwardly ;upon the rod "26 causing the thread hook B to entertne flared portion'lfi' of the spindle, and subsequently the main cylindrical bod-y'portion 15 thereof. After thethre'ad hook has completed its upward movement 'the'same rests substaintiall'y stationary while the needle rod 17 115 moves in a downward direction, causing the trated or described. In order .to provide a means whereby the slide 27 may reciprocate upon the pin 26, any suitable lever connection 37 is interposed-between the outer side "of saidslide and the timing mechanism, -which is'notillustrated or described by reabearing- 12, said ,rod having a slide 27 mounted for reciprocation thereon. A de- 48 pendent bracket 28 is pivotally mounted on ne'side of the slide. 27 and cooperates with the clamping plate 29, which rigidly secures 'hook to said bracket. I u 00 nthe machine is in operation at foilI* hundred (1400) or more revolutions per; minute, the tendency of the bracket 29'" i is tovibra'teand form a somewhat Irregular stitch. To overcome tendency and 'needle 18fto pierce the'goods and enter the cylinder15 to meet the hook 35 of the thread hook B. As the needle 18 reaches the i RdQthe bracket 28, and. at-flthe opposite lowestpoint of its movement, and simultaneousgwith the starting of "the forward movement thereof, the slide '21 moves slightlyto the right, causing a similar motion in the hook 35 ofthe thread hook B, I in order that the said hook may engage the loop of thread carried by the needle 18. It ,will be understood that the slide 27* then moves downwardly upon the rod 26, bringwith fit the thread 38 originally carried l bythe needle until said slide has nearly 55 Provide a means whereby positive rigidity may l e-assured, a spring 30 1S -S3Cll1t3d at one T terminal thereof between the ,clampmgplate z'terminal is attached bya screw 31 to the 60's'lide 27.
